Citizen 37AD3-U AC Adapter w/ Power Cord

Overview

The Citizen 37AD3-U is a direct AC power adapter with integrated power cord designed for Citizen CT-S6XX and CT-S8XX series thermal printers. This adapter replaces or supplements the original power supply in fixed-location deployments where AC mains connection is required. Typical use cases include retail point-of-sale stations, shipping label stations, and warehouse receipt printers where the printer sits on a fixed counter or mounting bracket and needs stable, continuous AC supply.

Compatibility

The 37AD3-U is engineered specifically for the Citizen CT-S6XX and CT-S8XX thermal printer families. Do not attempt to use this adapter with other Citizen printer series or third-party equipment — voltage and connector specifications are tuned to these models only. Verify your printer model before ordering; check the nameplate on the rear or base of your unit.

Installation Notes

Connect the adapter's plug to a standard AC outlet and attach the mating connector to the power inlet on the printer. Ensure the outlet is grounded and rated for the required amperage. Keep the power cord routed away from thermal print heads and ribbon cartridge areas to avoid heat damage. Position the adapter so the cord does not create a tripping hazard in the work area. If your printer is installed in a mobile or portable configuration, consider securing the cord with cable clips or tape to prevent accidental disconnection during operation.
